As of rxjs 5 you can use the built-in websocket feature which creates the subject for you. It also reconnects when you resubscribe to the stream after an error. Please refer to this answer:

TLDR:

 let subject = Observable.webSocket('ws://localhost:8081');
 subject
   .retry()
   .subscribe(
      (msg) => console.log('message received: ' + msg),
      (err) => console.log(err),
      () => console.log('complete')
    );
 subject.next(JSON.stringify({ op: 'hello' }));
